Hello Everyone,

I picked up my car yesterday. I took a picture of the coolant tank before leaving the dealership. They did put a black line on the tank where the coolant level is now, which is maximum. I will go ahead and drive and monitor. I read the paperwork and not one place did the dealer service rep. state that he seen the coolant tank basically empty. That is what frustrated me more than anything. As I previously mentioned I popped the hood and made him look at it. So the paper work reports the customer states the coolant level is below minumum, then it goes to the mechanics notes that the coolant tank was at minumum. Maybe I don't know how to check the level on these new cars. For many years I maintained my cars and I never seen coolant go from the bottom of the tank to the minumum line after driving it 20 miles. In the end at this point it does not matter anymore. I will let everyone know if the level drops again. By the way there was no charge for the diagnosis of no problem found.

Yesterday I opened the hood of my ford and for the first time did a complete (look see feel) first step in troubleshooting I noticed the coolant over flow tank cap marked 21psi Im assuming this tank is pressurized (please if im wrong feel free to correct me) The old style tanks were not they were just containers that collected overheated coolant released by the thermostat. As the coolant cooled it was drawn back into the radiator. the new tanks (Plastic see thru) appear to be a integral part of the cooling system. The tank had a rubber inlet hose at the top and what appeared to be a rubber vent hose that went back to the top of the radiator. The inlet was wet with coolant the vent outlet was clean and dry. On the bottom of the plastic tank was a large hose that i felt went back to the radiator. On the top of the tank was the cap marked 21 psi. All these connections could propose a leak. The thing that intrigued me was the vent line disappearing into the top of the radiator. Look at the tank vent if the tank vent outlet is wet follow it to the top of the radiator look down there appears to be a large opening with a floor mine was dry. The key here if the tank overflows from high pressure where dose the coolant go.

Thank you sirdrivealot, I will take a closer look at mine.

Hello Everyone,

I have an update to my 2020 1.5l Dragon engine coolant leak. Once again my coolant level dropped. This time I took it in when the level dropped between the max and min line. As I mentioned in a previous message the dealership filled my empty reservoir back in February of this year to the Max line. The level stayed at the line they made until roughly a month ago. Once again the dealership did the pressure test and once again no problem found. I asked again is this normal, same deer in the headlight look with no answer. They said bring it back if it goes below min line. The last conversation I had with a Ford rep left me no suggestions and left me angry telling me I should be paying for the time involved troubleshooting their issue. I ended up buying the extended warranty. We will see what happens. If they don’t stand behind this I may have to get rid of this car if I can, even at a loss. They did not even stand behind what they told me back in February of this year; they said they would do more than a pressure test, they would not do it.

I will let you know if something changes.

I'm having coolant loss issues on our 2020 Escape 2.0. Dealer topped off all fluids during an April '23 checkup. In late November we were not getting and heat.....no coolant in reservoir! November 28 in for "The Works", pressure tested cooling system, tested OK, topped off fluids. 700 miles later coolant level was down 1/2" to 3/4". Vehicle is going in for more analysis on January, 3, 2024

As it turns out the coolant leak was in the EGR valve. The valve was replaced under warranty.

Thank god...it would be discouraging if the later engines suffered from coolant intrusion too.

Thanks for info.

Is the EGR valve the same as the Vapor Management/Canister Purge Valve and line assembly? Another dealer just replaced this on my vehicle but the repair wasn't for the leaking coolant? I've had the coolant go below minimum 3 times since I've had the car (New 1.5 3cyl 2020 now 36K miles). The car was pressure tested 3 times for the leak and they found nothing. They replaced this valve as I've had a regular issue with a ticking/tapping sound (annoying as hell) when the car is cold slowing from 65mph-40mph without gas pedal. But when the pedal is pushed, the sound stops. That issue remains, but I likely won't know if that addressed the coolant issue for another 10k miles or so?

Hello Stustoner, I am curious about the EGR issue. Did you have a puddle of coolant at anytime? Did the pressure test find the faulty EGR valve?

 

[stustoner]

There was never any evidence of a leak/puddle on the garage floor. I was told that the EGR valve was allowing coolant to leak into the exhaust system and was then burnt off. I do not know if they found the leak via pressure testing. I am monitoring the coolant reservoir to ensure that the EGR fix corrected the issue.

Thank you for the quick response.

I have had two instances where I took my Escape in for coolant loss. Both times the pressure test showed no issues.

I wonder if there is away of telling by looking at the tailpipe if you are losing coolant into the exhaust? I am going to do some more investigating on the coolant leaking into the exhaust.

I was also suspicious of a water pump leak. A few people on the Bronco forum had reported water pump leaks that left no puddles on the ground. By the way these are Bronco Sport owners, which have the 1.5l 3 cylinder dragon ecoboost engine like we do.

Look for coolant underneath water pump.

To our absolute horror our 2020 began exhibiting the disappearing coolant act that our 2017 did. We had a 2017 we got rid of because it had the same problem/fix TWICE in 36,000 miles and now we’re back to square one.

Two weeks ago our 2020 went into the dealer after noticing the coolant was well below minimum. 16,000 miles on it total. We had already scheduled a visit because of some other issues we were having (interior noises etc, nothing ‘major’) but showed them the coolant. After two weeks they have found the block is cracked and they have a new one on order, with no ETA.

Super frustrated with Ford at this point. I’m a Ford employee, and I’m also dealing with another battle on another front (my Bronco Sport left me stranded with only 200 miles on it and is still being diagnosed). I couldn’t be sicker about all this.

Has anyone else in the 4th gen community had coolant problems? And if no you guys may want to start monitoring it. We had no leaks, no smells, no odd behaviors mechanically. Nothing that would’ve flagged it. Car is driven by my wife, 80% highway across town, has had no sort of rough life. Been serviced timely and at the dealer etc

Praying this is a one off defect and not a sign that the 3g problems have carried over.

My 2022 Ford Escape SE 1.5 coolant level was below the minimum line. Just added 1 1/2 cups of Ford antifreeze @ 10,000 miles. Waiting to see if it continues.

Well I received a call back from the dealer. They say my car past the pressure test they run on the coolant system. That means coolant is not going into the cylinders. The thing is right now he can not tell me why my coolant level was low. Is it normal to have the coolant level drop from minimum to not visible, that is below the minimum line. The coolant was at minimum a month ago. View attachment 82955

I know this is old but did you ever find out why your coolant in your reservoir was low ?

[mozzman]

Our 2021 was low when we bought it used, 15k miles. I had them top it off. Appears good since then but i can swear it had a air bubble in the system. The temp was always slow to rise but was fine once you drove it a while. Today it appears to be coming up to temp quicker so i am going on the air bubble thing and hopefully it worked it's way out.

The 1.5L L3 Dragon is a cold hearted beast that's slow to warm up.
Hence the reason every Escape 1.5 L3 built for the lower 48 not being delivered to the SE/SW US markets come with a ceramic PTC in the defrost plenum.
